2 Claims.

It has been common practice in metal building structures to employ side wall panels of one thickness of steel. These radiate heat easily so that the building is apt to become excessively hot in summer and cannot be economically heated in winter.

The object of the present invention is to provide a panel or wall structure particularly designed for buildings, though not restricted to such use and in which an insulating bodyis protected by metal facing plates, the structure being simple in character and involving the promanufactured and easily assembled, the elements of the members furthermore being effectively held in assembled relation.

A further and important object is to provide a structure that is practically sealed against the absorption of moisture so that whether the panel members are exposed to water or dampness before or after installation, they are not subject to the deleterious effects that are apt to arise by reason of excessive moisture contained therein.

In the accompanying drawings:

Figure 8 is a of the U-ties.

In the embodiment shown in Figures 1, 2 and 3, portions of two associated panels are illustrated, the panels being duplicates and designated generally by the reference numeral 8. Each of these panels consists of a sheet or slab of heat insulating material 9, forming the body of the panel and of any well-known relatively porous material. Commercial products may be employed for the purpose. Each body 9 has secured to its opposite sides metal facing plates l preferably united to the body 9 by an adhesive Illa. The plates at their lower ends extend beyond the body 9, providing flanges H that desectional view on the line detail perspective view of one fine between them and the bottom edge of the body 9, a channel or groove l2. The upper end of the structure is formed to fit in the groove of the overlying panel and in the structure shown as the flanges H lie in the same plane as the main portions of the facing plates ID, the upper margins of said facing plates are inset, as shown at l3, and these terminate at the upper edge of the body. The result is that a tongue portion is formed which will fit the groove l2, and 10 the facing plates of one member lie in the planes of the plates of the other members.

In-order to strengthen the lower groov d ends of the members and prevent the projecting flanges being forced apart and thereby separated from the .body, ties are employed. These ties are shown in the form of rivets l4 that pass through the body 9 adjacent the groove l3 and have heads l5 upset over the outer sides of the facing plates. The structure is thus adequately reinforced so that there is no danger of the plates being torn away from the body.

The body or slab 9 being ordinarily of porous or cellular material, ,if exposed to the atmosphere and especially to rain, would absorb considerable moisture through its exposed end and side edges. This is obviously true for no matter how carefully protected when packed, it would none the less be exposed to atmospheric conditions and furthermore it often lies about before 30 being installed. And indeed a sudden rain during installation operations will wet the uncovered edges. In less measure even after a wall of the panels is completed, a leak at a joint will give water access to the heat insulating body. 5

And when moisture finds a place therein, difficulty ensues because in freezing and thawing expansion and contraction takes place that may be suflicient to pry the facing sheets loose.

To prevent the entry of moisture therefore, the raw or exposed edges of the insulating body are substantially waterproofed and any suitable material may be used for the purpose as sodium silicate, rubber cement, asphalt mixtures, paraffin or Montan wax. The most satisfactory covering so far discovered however has been created by giving the exposed edges of the body 9 a foundation coat of sodium silicate and covering this with a coat of paint. These can be applied with a brush or as a spray. Such coating is indicated at l5a and produces a somewhat elastic or yielding covering on the edges that is practically impervious to moisture and by impregnating the portion of the body directly adjacent to the surface, is eifectively bonded thereto.

Aswill be clear by reference to Figures 1 and 2, in assembling a wall of these panels, the upstanding tongue portion of one panel is received in the groove of the panel above it, thereby effectively interlocking the panels and providing a horizontal waterproof joint between them. The structure is particularly useful for the external walls of metal buildings because of the heat insulating qualities. The insulating bodies, however, are fully protected against wear and weather. The structure moreover is one that adapts itself toeconomical manufacture and installation. Though particularly useful for building walls, it is obvious that it may be employed for various other purposes.

A modification of the structure is shown in Figures 4-7 inclusive. In this embodiment each panel 16 has a body or slab ll of insulating material covered by metal facing-plates i8 adhesively secured to its opposite sides. The facing plates have their lower margins extended as shown at 59 and provide flanges forming between them a groove. These flanges have their free margins inturned as illustrated at 2t, providing lips and internal channels. Ties U-shaped in cross section and of sheet metal connect the flange portions and are designated 2i. They lie flat against the lower edge of the body El and have downturned terminals 22 that are engaged in the channels behind the lips 20. A plurality of these ties is preferably employed as illustrated in Figure 7, being spaced apart. The upper margins of the panels are preferably reduced in cross section to provide tongues 23 that fit in the grooves of the over-extending panels. The waterproof coat for the edges is shown at 24. The structure, it will be noted, has the same advantages of that first described in that the insulating body is effectively protected by a waterproof covering and the projecting margins or flanges are directly tied together and are thus positively held against separation and against being disengaged from the body.

By referring to Figure 5, it will be noted that when two of the units are assembled, the joint structure between them constitutes in effect an I-beam that reinforces the structure. That is to say the parts 2| and 24 of the metal sheathing together constitute the web of such I-bearn, the flanges i920 of one unit and the inset flange portions of the facing sheets l8 of the other member constitute flanges at one side of the web 2 l and 24, while the portions of the facing sheets I 8 of the first member that overlie the body I! constitute the opposite flanges of such I-beam structure. Incidentally the bodies I! may properly be termed slabs.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art without further descrip tion, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

What I claim, is:

l. A composite board comprising a body of insulating material, metal sheets covering opposite sides of the same and projecting beyond one edge to form a channel for receiving the edge of an adjacent body, adhesive securing the metal sheets to the adjacent faces of the body, and tie devices connecting the metal sheets adjacent their projecting ends and acting to prevent their being spread apart and. the destruction of their adhesive attachment to the body by the insertion of an adjacent board.

2.
